tkinter.ttk is a module that is used to style the tkinter widgets. Just like CSS is used to style an HTML element, we use tkinter.ttk to style tkinter widgets.Here are the major differences between tkinter widget and tkinter.ttk −Tkinter widgets are used to add Buttons, Labels, Text, ScrollBar, etc., however, tkinter.ttk supports a variety of widgets as compared to tkinter widgets.Tkinter.ttk doesn't support Place, Pack() and Grid(), thus it is recommended to use tkinter widget with ttk.Ttk has many features and configurations that extend the functionality of a native application and make it look more modern.Tkinter widget is a native ...

Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. It is collection of nodes.Node has two parts which are as follows −DataLinkTypes of Linked ListsThe types of linked lists in C programming language are as follows −Single / Singly linked listsDouble / Doubly linked listsCircular single linked listCircular double linked listAlgorithmRefer an algorithm given below for storing the car information by using the dynamic linked list.Step 1 − Declare structure variables.Step 2 − Declare Function definition to display.Step 3 − Allocate dynamic memory allocation to variable.Step 4 − Use do while loop to enter the car information.Step ...

In C programming language, we can find the area of circle, area and volume of cylinder with the help of structures.The logic used to find area of circle is as follows −s.areacircle = (float)pi*s.radius*s.radius;The logic used to find area of cylinder is as follows −s.areacylinder = (float)2*pi*s.radius*s.line + 2 * s.areacircle;The logic used to find the volume of cylinder is −s.volumecylinder = s.areacircle*s.line;AlgorithmRefer an algorithm given below to find the area of circle and cylinder along with other parameters by using structures.Step 1 − Declare structure members.Step 2 − Declare and initialize the input variables.Step 3 − Enter length and ...

Anagram strings are nothing but, all the characters that occur for the same number of times in another string, which we call as anagrams.A user enters two strings. We need to count how many times each letter ('a' to 'z') appears in them and then, compare their corresponding counts. The frequency of an alphabet in a string is how many times it appears in it.If two strings have same count of the frequency of particular alphabet then, we can say those two strings are anagrams.Example 1String 1 − abcdString 2 − bdacThese two strings have same letters which appear once. ...

In C programming language, nCr is referred as the combination. nCr is the selection of r objects from a set of n objects, where the order of objects does not matter.nPr is referred as the permutation. nPr is arrangement of 'r' objects from a set of 'n' objects, which should be in an order or sequence.Permutations and combinations formulasThe formulas to find the permutation and combination of given numbers in C language are given below −nCr = n!/(r!*(n-r)!)nPr = n!/(n-r)!.The logic used to find nCr is as follows −result = factorial(n)/(factorial(r)*factorial(n-r));The logic used to find nPr is as follows −result ...

Intersection operationIf array 1 = { 1,2,3,4,6}  Array 2 = {1,2,5,6,7}Then, intersection of array1 and array 2 isArray1 ^ array 2 = {1,2,3,4,6} ^ {1,2,5,6,7}         = {1,2,6}Set of common elements is called an intersection.The logic for intersection is as follows −k=0; for(i=0;i

A union is a special data type available in C programming language that allows to store different data types in the same memory location. Unions provide an efficient way of using the same memory location for multiple-purpose.Union operationIf array 1 = { 1,2,3,4,6}    Array 2 = {1,2,5,6,7}Then, union of array1 and array 2 isArray1 U array 2 = {1,2,3,4,6} U {1,2,5,6,7}                              = {1,2,3,4,5,6,7}Set of all elements without repetition is called union.The logic for union is as follows −for(i=0;i

User has to enter number of names, and those names are required to be sorted in alphabetical order with the help of strcpy() function. An array of characters (or) collection of characters is called a string. Declaration Following is the declaration for an array − char stringname [size]; For example, char string[50]; string of length 50 characters. Initialization Using single character constant char string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’} Using string constants char string[10] = "Hello":; Accessing There is a control string "%s" used for ...

An assertion is a statement which is used to declare positively that a fact must be true when that line of code is reached.Assertions are useful for obtaining the expected conditions which are met.Simple AssertionSimple assertion can be implemented by using assert (expression) method, which is present in assert.h header file.The syntax for simple assertion is as follows −assert(expression)In simple assertion, When the condition passed to an assertion which is a true, then, there is no action.The behaviour on false statements depends completely on compiler flags.When assertions are enabled, a false input causes a program to halt.When assertions are disabled, ...
